We will show that microwaves reflected from and transmitted through a porous media have a fractal dimension correlated to that of the porosity. The fractal signature of the scattered microves correlates well with some physical and mechanical properties of porous media. A mathematical model relating the ground penetrating radar record to the mass fractal dimension of the soil structure is also developed.

Plenary Lecture 2:

The Role of Global Optimisation in Oil-Reservoir Production Forecast

Prof. Susana Gómez Gómez
IIMAS. UNAM.

To be able to forecast the production of a reservoir (water and oil), it is necessary to simulate the flux, which implies the characterization of the porous media of the site under study. Using historical data on the pressure and saturation, this problem of coefficient identification, can be solved as an ill- posed inverse continuous least-squares optimisation problem. The optimisation of this inverse problem, may have many local optima with good match to the data, which produce alternative scenarios of production. These alternative solutions also provide a way to deal with the uncertainty of the modelling process. Also, due to the non-continuity of the inverse operator, it is necessary to use regularization methods to get stable solutions in the realistic case of historical data with measurement errors. Our aim here, is the generation of alternative global optimisation methods that obtain the optimal solutions with good match to the data in a stable way, and in reasonable computer time, to produce efficient decision making tools.
We will present here the Parallel Tunneling Global Optimisation method, that performs multiple Levenberg-Marquard type local searches, to produce local optimal solutions with good match. Also, an alternative method to regularize and the need to efficiently scale the problem, will be discussed. The speed and robustness of the method will be shown when tested on synthetic and real reservoirs.
